The gradient of the velocity–time graph on page 40 has a constant value; it represents a constant or uniform acceleration. A number of equations link the variable quantities when an object is moving with uniform acceleration. They are: v = u + at s = ut + 1/2at2 v2 = u2 + 2as ...
In uniform motion, the same distance is traveled in the same interval of time. Furthermore, there is zero acceleration. Because the speed is not changing over time, the average speed of an item moving with uniform motion is also the speed that the item is moving at. What...
The First Equation of Motion that relates the velocity and time of the object in uniformly accelerated motion along a straight line is derived graphically as given below: The velocity-time graph of an object that is moving with uniform acceleration along a straight line is given below: ...
When an object travels in a straight line and covers the same distance at the same time, it is said that the object is in uniform motion. Simply, the rate of change in velocity will always remain constant in the case of uniform acceleration.

Acceleration and non-uniform motion P-T Graph P-T Graph Velocity and Acceleration have SAME sign: object is SPEEDING UP Velocity and Acceleration have OPPOSITE sign: object is SLOWING DOWN Acceleration is calculated as the change in velocity over the change in time. Acceleration has units of dis...
Do objects moving in uniform circular motion have constant speed? Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its...
Which type of acceleration occurs in circular motion? In which direction does centripetal force point? Is static friction the same as the centripetal force? Figure 1 shows the angular-position-versus time graph for a particle moving in a circle. A) What is the p...
